The low flow regulator flows oxygen from 1/32 to 4 liters per minute. It's required if using an industrial oxygen tank in North America and select countries (international info below). This regulator will only work on a CGA-540 tank.

Flow sequence is 1/32, 1/16, 1/8, 1/4, 1/2, 3/4, 1, 1.5, 2, 3, 4. The low flow regulator operates at 50 psi.

Important Notes (all users)

The maximum pressure allowed in these regulators is 2600 psi. Many countries in Europe, Australia and a few others will typically fill beyond that (3000+ psi). You will need to discuss this with the oxygen tank supplier to ensure the pressure is well below the max limit to ensure the regulator isn’t compromised and no longer usable. Promolife is not responsible if the regulator is used with a higher pressure and damaged. A new regulator would have to be purchased.

Upon receipt of this item and before using, it is very important that you read the instructions in their entirety.
